Phalaenopsis plant named ‘SUPHAL1301’

ABSTRACT

A new and distinct  Phalaenopsis  cultivar named ‘SUPHAL1301’ is disclosed, characterized by very distinctive deep Greyed-Purple and brown flower color, small plant size and dark stems. The new variety is a  Phalaenopsis , typically produced as an indoor ornamental plant.

Latin name of the genus and species: Phalaenopsis hybrid.

Variety denomination: ‘SUPHAL1301’.

BACKGROUND OF THE INVENTION

This application relates to a new cultivar of Phalaenopsis hybrid. The new variety is the product of a planned breeding program. The new variety originated as a seedling from the crossing of the unpatented, proprietary seed parent Phalaenopsis ‘TB637’ with the unpatented, proprietary pollen parent referred to as Phalaenopsis ‘TB642’. The crossing was made by the inventor in his research greenhouse in Chonburi, Thailand in March of 2006.

The new variety was first selected by the inventor, Thumrong Suphachadiwong, a citizen of Thailand, in July of 2009 in a research greenhouse belonging to the inventor in Chonburi, Thailand. After identifying the new variety as a potentially interesting selection, the inventor continued confidential testing and propagation of ‘SUPHAL1301’, assessing stability of the unique characteristics of this variety.

Asexual reproduction of the new cultivar ‘SUPHAL1301’ was first performed at a commercial laboratory belonging to the inventor in Chonburi, Thailand by tissue culture in August of 2009. Access to all plants was restricted, as plants were kept in a greenhouse not open to the public, and tissue culture plantlets were in a laboratory belonging to the inventor, and not accessible to the public. Through subsequent propagation, multiple generations have been reproduced, which have shown that the unique features of this cultivar are stable and reproduced true to type.

SUMMARY OF THE INVENTION

The cultivar ‘SUPHAL1301’ has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, day length, and light intensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘SUPHAL1301’. These characteristics in combination distinguish ‘SUPHAL1301’ as a new and distinct Phalaenopsis cultivar:

-   -   1. Very distinctive deep greyed-purple and brown flower color.     -   2. Small plant size.     -   3. Unique dark peduncles.

PARENT COMPARISON

Plants of the new cultivar ‘SUPHAL1301’ are similar to the seed parent, Phalaenopsis ‘TB637’ in most horticultural characteristics. The new variety, however, produces a darker flower color than the seed parent.

Plants of the new cultivar ‘SUPHAL1301’ are similar to the pollen parent, Phalaenopsis ‘TB642’ in most horticultural characteristics. Plants of the new variety however, are more compact plant with darker colored leaves than the pollen parent.

COMMERCIAL COMPARISON

‘SUPHAL1301’ is similar to the unpatented commercial variety Phalaenopsis ‘Zaragoza’ in most horticultural characteristics. However the new variety, ‘SUPHAL1301’ has a much smaller flower and leaf size as well as a shorter plant height than comparator ‘Zaragoza’. Additionally the new variety ‘SUPHAL1301’ produces a lip, sepal, petal, and side lobe of different shape than those of comparator ‘Zaragoza’. Also the new variety ‘SUPHAL1301’ produces a flower of darker coloration and leaves of different angle than those of comparator ‘Zaragoza’.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photograph in FIG. 1 illustrates in full color a typical plant of ‘SUPHAL1301’ grown in a commercial greenhouse in Zuidbroek, the Netherlands. This plant is approximately 18 months old after deflasking, shown planted in an 11 cm container.

FIG. 2 illustrates a close up of the individual flower. The photographs were taken using conventional techniques and although colors may appear different from actual colors due to light reflectance it is as accurate as possible by conventional photographic techniques.

DETAILED BOTANICAL DESCRIPTION

In the following description, color references are made to The Royal Horticultural Society Colour Chart 2007, except where general terms of ordinary dictionary significance are used.
